摘要：
In a method for addressing rows and columns in a liquid crystal display, each phase for addressing rows and columns in the display includes precharging pixels of the display before a row write, to apply a precharge voltage to all pixels. Depending on the selected black or white precharge level, the light box is either switched on permanently, or is switched on during each addressing phase immediately after the precharge or immediately after the row write. The display brightness is thus improved. The display may be of sequential color type.
